Abstract PGE03 6.1.12; PGE03 V6.0.51; PGE06 6.1.6 -- Add new set of Cloud products in regular and polar projections
Problem Statement Changes have been made to the GDAS atmospheric profile that are used as ancillary data in the cloud top properties algorithm (MxD06_CT). To accommodate the changes in GDAS the MODIS Cloud Mask algorithm (PGE03) and the Cloud Top Properties algorithm (PGE06) had to be modified.
Description of Change Changes were made to gfs_routines.c and adjo3.c to account for modifications in GDAS input files. The numbers of levels have increased and RH and O3 levels are no longer contiguous with temperature levels. This required logic changes in the two routines.
Products Affected MxD06_CT
Software Affected PGE03 v6.1.2; PGE03 V6.0.51; PGE06 6.1.6
Processing String to Receive the Change Terra and Aqua Forward Processing. NRT
Downstream Product Effects MxD07_L2 and MxD08_D3, MxD08_E3, and MxD08_M3
Data Granules to be Used for Science Testing Science test generated nearly a month of Terra and Aqua data and were verified for correctness.
Justification Changes were made to gfs_routines.c and adjo3.c to account for modifications in GDAS input files. The numbers of levels have increased and RH and O3 levels are no longer contiguous with temperature levels. This required logic changes in the two routines.
Effective Date for Implementation of Change June 12, 2019
Status Major algorithm development completed. Michael King approved 06/18/2019. Steve Platnick approved 06/18/2019. Gang Ye implemented on 06/12/2019.
